GoDuo Buds

  • Can I use GoDuo speakers while they are being charged?
    Yes. Whether or not they are being charged does not affect your use of GoDuo speakers.
  • What devices can GoDuo work with?
    Any Bluetooth enabled devices, such as mobile phones, tablets, computers (both Windows and Mac), game consoles, etc.
  • Can I use GoDuo with my Amazon Alexa devices, such as Echo Dot?"
    Any Bluetooth enabled devices, such as mobile phones, tablets, computers (both Windows and Mac), game consoles, etc.
  • How can I tell if one speaker is the left channel or right channel?
    When the two speakers are in stereo mode, there are two ways to find out which speaker is the left channel. 1. During standby mode, observe the indicator light on the back of the speaker. On the left channel speaker,the light flashes every 5 seconds; on the right channel speaker, light flashes every 8 seconds. 2. When there is an incoming call, while you are in the call, or when you are dialing, if the indicator light on the speaker flashes rapidly, then the speaker is the left channel; otherwise it is the right channel. 3. If your GoDuo speakers are connected with iPhone, iPod or iPad, double-press the button on one speaker - if Siri is activated, then the speaker is the left channel; otherwise it is the right channel. 4. Power off both speakers and power back on. If the voice prompts are enabled, each speaker will anounce which side it is.
  • How can I mute the voice prompts/instructions?
    The new version of GoDuo speakers supports muting voice prompts. When the speakers are paired to each other but not with any other devices (you may disable Bluetooth on your phone to make it work), triple press on each speaker's multi-function button. You will hear "English selected", "Espanol seleccionado" or "voice instruction muted", which means the voice prompts are in English, Spanish or disabled.
  • Can I pair 4 speakers (two sets of GoDuo) at the same time?
    Although GoDuo speakers are not designed for syncing wirelessly by 4 speakers, you can make it work in either of the following ways. 1. Use audio split (Y-shape) cable. For the split side (two plugs), connect each plug to one speaker of a pair, and leave the other one sync via wireless. Then the four speakers will play music from the same source. 2. If you use Samsung Galaxy S8/S8 Plus/Note8, two sets of speakers can connect to your phone and play music at the same time. On your Samsung Galaxy phone, enable "Dual audio", then you can connect with two pairs of speakers and play the same music on them simultaneously. The latest generation of iPhone (iPhone 8/8 Plus/X) have not supported this feature of Bluetooth 5.0 yet. You will have to use Bluetooth splitter transmitter (connects to two audio devices at the same time or some special app to play music on four devices simultaneously. Either way, you will have two speaker units playing stereo music (two playing left channel and two playing right channel).
  • What warranty does KNZ support for GoDuo speakers? And how to file a warranty claim?
    GoDuo speakers are covered with 1-year limited manufacturers warranty starting from the original purchase date. For details please check
  • My GoDuo stopped charging?
    The early version of GoDuo speakers are designed to use qualified (with safety certification) chargers, such as UL listed power adaptors. Using un-certified aftermarket chargers might damage the charging circuit in the speakers. In later versions we improved the charging circuits to be compliant with more aftermarket chargers. However in order to protect your property, we strongly suggest charging GoDuo speakers with qualified chargers/power adapters.
